A robber wearing a white construction hardhat and what appeared to be a varsity jacket used a note to rob the Northfield Bank Branch at 385 Bay Street in Stapleton Tuesday morning, according to police.

The suspect walked in about 11:08 a.m., pretended he was going to get a withdrawal slip, then went up to a teller and produced a demand note, NYPD sources said. The teller handed him several thousand dollars, and he left on foot, sources said.

The suspect is described as a black man, between 25 and 30 years old, about 5 feet 8 inches tall, with a medium or light build, according to an NYPD source familiar with the investigation.

His clothing was distinctive, the source said -- the aforementioned hardhat and jacket, as well as blue jeans with the cuffs rolled up.

It's the second time that branch has been robbed this year -- on March 4, a bandit walked into the place, passed a threatening note, and left with cash, police said.
